A téma rövid leírása, a kidolgozandó feladat részletezése:
Fiber-reinforced polymer (FRP) has been extensively used in many fields of the industry. The high strength, light weight, non-corrosive properties, rapid construction, and low maintenance requirements make FRP an attractive solution also for civil engineering. However, to overcome the relatively low stiffness, local weakness, and initial high cost of beams made entirely of FRP, the possibility of using FRP–concrete composite beams or floors has been raised recently. This kind of composite structure maximizes the advantages of both FRP and concrete. FRP behaves as the main girder on the tensile side while concrete deck in compression, enhancing the global stiffness and resistance to concentrated load. After considering the expected improvements in transport, installation, and life-cycle differences, the initial cost of FRP can be offset, thereby leading the system competitive to conventional solutions. The aim of the research is the analytical and numerical examination of FRP–concrete composite floors for building construction by different configurations, regarding the specific material properties of the FRP, long term behavior of concrete and the connection interface between FRP and concrete.
The candidate must solve the following tasks:
• Literature review: (i) material properties and analysis of FRP material; (ii) long term behavior of concrete; (iii) analysis of composite floor systems (also made of other materials like steel-concrete or wood-concrete composites) including connection interface; (iv) overview of available FRP-concrete composite floor solutions; (v) methods for numerical modeling of FRP material, composite floor systems and connection interfaces.
• Evaluation a comparative analysis of existing FRP-concrete composite floor solutions. Recommendations for the possible enhancement of existing solutions or new possible solutions. Consideration of different FRP materials (GFRP, CFRP, etc.) and construction techniques with and without the need of formwork (e.g. FRP beam also acts as a formwork, or combination FRP beam and prefabricated concrete formwork panels).
• Analysis of the selected floor system(s) using analytical approach based on literature review.
• Numerical analysis of the selected floor system(s) taking into consideration the realistic material behavior of FRP, long term behavior of concrete, and the connection and force transfer between FRP and concrete. After validating the numerical model, parametric analysis may be performed to find the most effective and economical floor configurations.
• Comparison and evaluation of the results.
